Samsung 25R - 18650 Flat Top Battery

Samsung 2500mAh 20A 3.7v Rechargeable Flat Top Batteries

These are the latest "Green" version of the lauded Samsung 25R 18650 flat top battery. The green version of the battery is reported to have a lower internal resistance per Samsung and as such should run cooler than the previous blue-wrapped variant. This battery will work extremely well with all of your sub-ohm mods. Rock Bottom Vapes strongly discourages the use of mechanical mods unless you are very well versed the potential dangers (and how to avoid them) of Lithium cells on non-regulated mods.
